Building a large scale data center is not an easy task and one that includes considerable cost. The larger the cluster is, the larger the core switching element needs to be to carry traffic between servers and storage elements of the data center. Multiple redundancy and distribution mechanisms are needed to avoid network outages, […]

Covered in previous blog posts (Part 1 and Part 2), the concept of the Virtual Modular Switch (VMS) is clearly an advantage for networks of medium to large scale. As we move into huge networks where multiple modular switches are needed, this advantage reduces to the point where it is a matter of personal preference […]

If you search the internet for data center automation tools, you will come up with many options. You can easily find software tools that automate server provisioning, network equipment configuration or monitor the different elements. But you cannot find tools for automatic fabric configuration. Fabrics become more popular these days. If traditional aggregation switching in […]

Distributed elements, in any sector, have their basic benefits and drawbacks compared to a single large tool. It is similar to the preference of using small aircraft over a jumbo 747 for carrying passengers between proximate airfields or to using a bus vs. multiple private cars to move a football team around. In networking, […]

Traditionally, while Ethernet networks were serving low end and non-performance driven applications, the network topology was based on an access layer with a very high port count and a very low rate of traffic generation. This drove a very high and acceptable blocking ratio and a situation where a single (or two in case of […]
